Many works can be found in the literature concerning the vibroacoustic modelling of submerged stiffened cylindrical shells, because of high interest in the industrial domain, in particular for aeronautical or naval applications. However, only a few of them take into account non-axisymmetric internal frames, as for instance engine foundations or floor partitions, that can play a role on the vibr...

In this paper, the characterisation of elastic shear buckling behaviour simply supported plates diagonally stiffened excluding influence direct stresses is made. Two broad numerical parametric studies consisting linear analysis by finite element method are performed, covering entire practical range critical parameters like aspect ratio and stiffener’s mechanical properties. first study, attenti...
